2014-02-07mac80211_hwsim: fix number of channels in interface combinationsJohannes Berg1-1/+1
There's little point in setting the number of channels if the entire combination struct is overwritten again later - that was clearly intended the other way around, fix it. Reported-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-06mac80211: move VHT related RX_FLAG to another variableEmmanuel Grumbach2-4/+4

2014-02-05cfg80211: fix channel configuration in IBSS joinAntonio Quartulli5-10/+12
When receiving an IBSS_JOINED event select the BSS object based on the {bssid, channel} couple rather than the bssid only. With the current approach if another cell having the same BSSID (but using a different channel) exists then cfg80211 picks up the wrong BSS object. The result is a mismatching channel configuration between cfg80211 and the driver, that can lead to any sort of problem. The issue can be triggered by having an IBSS sitting on given channel and then asking the driver to create a new cell using the same BSSID but with a different frequency. By passing the channel to cfg80211_get_bss() we can solve this ambiguity and retrieve/create the correct BSS object. All the users of cfg80211_ibss_joined() have been changed accordingly. Moreover WARN when cfg80211_ibss_joined() gets a NULL channel as argument and remove a bogus call of the same function in ath6kl (it does not make sense to call cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

2014-02-05nl80211: fix scheduled scan RSSI matchset attribute confusionJohannes Berg2-5/+17
The scheduled scan matchsets were intended to be a list of filters, with the found BSS having to pass at least one of them to be passed to the host. When the RSSI attribute was added, however, this was broken and currently wpa_supplicant adds that attribute in its own matchset; however, it doesn't intend that to mean that anything that passes the RSSI filter should be passed to the host, instead it wants it to mean that everything needs to also have higher RSSI. This is semantically problematic because we have a list of filters like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which one should be OR'ed and which one AND'ed. To fix this, move the RSSI filter attribute into each matchset. As we need to stay backward compatible, treat a matchset with only the RSSI attribute as a "default RSSI filter" for all other matchsets, but only if there are other matchsets (an RSSI-only matchset by itself is still desirable.) To make driver implementation easier, keep a global min_rssi_thold for the entire request as well. The only affected driver is ath6kl. I found this when I looked into the code after Raja Mani submitted a patch fixing the n_match_sets calculation to disregard the RSSI, but that patch didn't address the semantic issue.

2014-02-05mac80211: add length check in ieee80211_is_robust_mgmt_frame()Johannes Berg4-4/+4
A few places weren't checking that the frame passed to the function actually has enough data even though the function clearly documents it must have a payload byte. Make this safer by changing the function to take an skb and checking the length inside. The old version is preserved for now as the rtl* drivers use it and don't have a correct skb.

2014-01-24sfc: Use the correct maximum TX DMA ring size for SFC9100Ben Hutchings2-2/+5
As part of a workaround for a hardware erratum in the SFC9100 family (SF bug 35388), the TX_DESC_UPD_DWORD register address is also used for communicating with the event block, and only descriptor pointer values < 2048 are valid. If the TX DMA ring size is increased to 4096 descriptors (which the firmware still allows) then we may write a descriptor pointer value >= 2048, which has entirely different and undesirable effects! Limit the TX DMA ring size correctly when this workaround is in effect.

2014-01-24net/cxgb4: Avoid disabling PCI device for towiceGavin Shan2-7/+21

2014-01-23IB/mlx5: Implement modify CQEli Cohen1-2/+15
Modify CQ is used by ULPs like IPoIB to change moderation parameters. This patch adds support in mlx5. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2014-01-23mlx5_core: Use mlx5 core style warningEli Cohen1-1/+2
Use mlx5_core_warn(), which is the standard warning emitter function, instead of pr_warn(). Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2014-01-23IB/mlx5: Clear out struct before create QP commandEli Cohen1-1/+1
Output structs are expected by firmware to be cleared when a command is called. Clear the "out" struct instead of "dout" which is used only later. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2014-01-23mlx5_core: Fix out arg size in access_register commandHaggai Eran1-1/+1
The output size should be the sum of the core access reg output struct plus the size of the specific register data provided by the caller. Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen updates from Konrad Rzeszutek Wilk: "Two major features that Xen community is excited about: The first is event channel scalability by David Vrabel - we switch over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO queue with priorities. This lets us be able to handle more events, have lower latency, and better scalability. Good stuff. The other is PVH by Mukesh Rathor. In short, PV is a mode where the kernel lets the hypervisor program page-tables, segments, etc. With EPT/NPT capabilities in current processors, the overhead of doing this in an HVM (Hardware Virtual Machine) container is much lower than the hypervisor doing it for us. In short we let a PV guest run without doing page-table, segment, syscall, etc updates through the hypervisor - instead it is all done within the guest container. It is a "hybrid" PV - hence the 'PVH' name - a PV guest within an HVM container. The major benefits are less code to deal with - for example we only use one function from the the pv_mmu_ops (which has 39 function calls); faster performance for syscall (no context switches into the hypervisor); less traps on various operations; etc. It is still being baked - the ABI is not yet set in stone. But it is pretty awesome and we are excited about it. Lastly, there are some changes to ARM code - you should get a simple conflict which has been resolved in #linux-next. In short, this pull has awesome features. Features: - FIFO event channels. Key advantages: support for over 100,000 events (2^17), 16 different event priorities, improved fairness in event latency through the use of FIFOs. - Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized disk and network, paravirtualized interrupts and timers, no emulated devices of any kind (and thus no qemu), no BIOS or legacy boot — but instead of requiring PV MMU, it uses the HVM hardware extensions to virtualize the pagetables, as well as system calls and other privileged operations." (from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum") Bug-fixes: - Fixes in balloon driver (refactor and make it work under ARM) - Allow xenfb to be used in HVM guests. - Allow xen_platform_pci=0 to work properly. - Refactors in event channels" * tag 'stable/for-linus-3.14-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (52 commits) xen/pvh: Set X86_CR0_WP and others in CR0 (v2) MAINTAINERS: add git repository for Xen xen/pvh: Use 'depend' instead of 'select'. xen: delete new instances of __cpuinit usage xen/fb: allow xenfb initialization for hvm guests xen/evtchn_fifo: fix error return code in evtchn_fifo_setup() xen-platform: fix error return code in platform_pci_init() xen/pvh: remove duplicated include from enlighten.c xen/pvh: Fix compile issues with xen_pvh_domain() xen: Use dev_is_pci() to check whether it is pci device xen/grant-table: Force to use v1 of grants. xen/pvh: Support ParaVirtualized Hardware extensions (v3). xen/pvh: Piggyback on PVHVM XenBus. xen/pvh: Piggyback on PVHVM for grant driver (v4) xen/grant: Implement an grant frame array struct (v3). xen/grant-table: Refactor gnttab_init xen/grants: Remove gnttab_max_grant_frames dependency on gnttab_init. xen/pvh: Piggyback on PVHVM for event channels (v2) xen/pvh: Update E820 to work with PVH (v2) xen/pvh: Secondary VCPU bringup (non-bootup CPUs) ...
